I need a plumber recommendation. Rheem water heater out, under warranty. Mostly likely the panel or heating element (tripping the breaker). Needs to be a licensed plumber that will submit the bill directly to Rheem, I have a warranty claim number. The one Rheem had contact me can only get to me next week! The plumbers I've used in the past either can't do it or not calling me back (ok, I'm impatient). Working on day 3 of cold showers and really want hot water!
